Hi there, I have not been on my dell Inspiron one 2330 for about 2-3 weeks now, I just turned it on and a sign appeared saying "No Video Detected on HDMI input." I can't see anything else beside the black background, I can't see my mouse, and I can't tap on anything. But if this helps, next to the words has a blue sign with a question mark beside a white sign of something? Please help!
